Preferred worm source?

[Nana2KJS]

As far as worms go, is there a prevailing opinion on the best of the bunch for a protein source?

Mealworms, black soldier fly larvae, red wigglers.. all can be "farmed" at home, but is any one better than another? Why?

There are probably as many opinions as there are worms; I'd just like to hear some pros and cons.

Honestly, I just dig out grubs from my garden... I never considered actually buying worms for my chickens...

mealworms have around 20% protein.

I just buy fishing worms from walmart as a treat for mine
